Question about LOS light on the ONT (singtel)

[hnzfaz]

Is the LED light on my ONT labeled as LOS supposed to be solid red? The others are all greenish/yellowish. Does red indicate that something is wrong? Btw, the internet seems to be working. Just wondering if the red LOS requires my attention.

Thanks in advance for any advice.

I got this red light after I exchanged for a new one. What should I do?

Don't be alarmed. If your Internet works fine, try rebooting the ONT.

If it turns on again, make sure the patch cord isn't kinked. Kinked patch cord causes signal loss and the ONT may interpret it as loss of signal when the value gets deranged.

If all things fail, perhaps you need to get it replaced too.
